DESCRIPTION

The M52727SP is an I2C bus interface built-in semiconductor IC designed to process PAL/NTSC type image signals, color signals and deflection signals. Provided with a switch for both S input and AV, black extension function, etc., the M52727SP can meet a wide range of devices from diffusion machines to large screen TV sets. The addition of SECAM chroma-decoder M52325AP will enable the M52727SP to completely and automatically identify the TV systems used all over the world.

FEATURES

• Is capable of reading/writing data with the I2C bus control circuit.

• Built-in AV-SW (with volume control) that is also available for S

input

• Complete and automatic identification of color signals and vertical

synchronous frequencies of a TV system

• Improvement in the synchronization separation facility at the time

of synchronous compression by auto slicer

• Built-in black expansion circuit

• Built-in vertical phase adjustment function

• Built-in two SW systems (ON/OFF by bus control)

APPLICATION

PAL/NTSC Type Color TV, Projecter
